The HMAT table is used to describe the memory attributes such as memory

The field validator function provides means to validate fields
in the ACPI table structures. To print complex field types a
print formatter function is provided.
The field validator was being invoked for simple data fields
for which the default print format is used. However, the field
validator function was not invoked if a print formatter function
was provided.
This problem is noticed when a Generic Address Structure (GAS)
is printed using DumpGas() and a field validator is present
to validate the GAS structure.
To fix this move the invocation of the field validator after
the field is printed such that the validation function is
called even when a print formatter function is present.

For Arm-based platforms, define and implement an interface for Server
Base Boot Requirements (SBBR) compliance checks. The library is
responsible for validating that all mandatory ACPI tables are installed
on the platform.
Internally, the library maintains a data structure which tracks
instance counts for ACPI tables which are labeled as 'mandatory' in any
SBBR specification version. The provided interface allows:
- resetting all instance counts to 0
- incremementing the instance count for a table with a given signature
- validating the instance counts against the requirements in SBBR
The ACPI table requirements for each SBBR spec version are represented
internally as a list of table signatures.
Every missing mandatory table (for the input SBBR version) is reported
to the user as a separate error. If all requirements are met, an info
message is displayed.

Extend validation of ACPI structure lengths which are read from the
ACPI table being parsed. Additionally check if the structure 'Length'
field value is positive. If not, stop parsing the faulting table.
Some ACPI tables define internal structures of variable size. The
'Length' field inside the substructure is used to update a pointer used
for table traversal. If the byte-length of the structure is equal to 0,
acpiview can enter an infinite loop. This condition can occur if, for
example, the zero-allocated ACPI table buffer is not fully populated.
This is typically a bug on the ACPI table writer side.
In short, this method helps acpiview recover gracefully from a
zero-valued ACPI structure length.

Remove duplicate Generic Address Structure (GAS) and ACPI table header

AcpiParser.h redefines the size of Generic Address Structure (GAS) and
the ACPI table header. The motivation is to 'minimise any reference to
the EDK2 ACPI headers in an attempt to provide cross checking'. While
the redefined values are unlikely to change, redefinition causes
unnecessary maintenance overhead for acpiview.
In addition to this, EDK2 ACPI headers are referenced throughout the

For fields outside the buffer length provided, reset any pointers,
which were supposed to be updated by a ParseAcpi() function call to
NULL. This way one can easily validate if a pointer was successfully
updated.
The ParseAcpi() function parses the given ACPI table buffer by a
number of bytes which is a minimum of the buffer length and the length
described by ACPI_PARSER array. If the buffer length is shorter than
the array describing how to process the ACPI structure, then it is
possible that the ItemPtr inside ACPI_PARSER may not get updated or
initialized. This can lead to an error if the value pointed to by
ItemPtr is later used to control the parsing logic.
A typical example would be a 'number of elements' field in an ACPI
structure header which defines how many substructures of a given type
are present in the structure body. If the 'number of elements' field
is not parsed, we will have a dangling pointer which could cause a
problem later.
